In order to establish a physician's liability, a plaintiff must prove that the physician deviated or departed from accepted community standards of practice, and that the alleged departure was a proximate cause of the plaintiff's injuries. Generally, expert testimony is necessary to prove a deviation from accepted standards of medical care and to establish proximate cause. The expert witness's opinions must be based on facts in the record or personally known to the witness.
